FURNITURE-JOINT.

s eHcrrIcArIoN forming part of Leners Patent No, 365,362, dated :rune 2a, 1887.

Application filed April 21, 1887. Serial No. 235,646.

the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperis adapted to loe applied to chairs, sofas, pi-

tains to make and use the same.

My invention relates to furniture-joints for attaching the legs to articles of furniture. It

anos, desks, tables, orlike articles; and it is my object to provide a joint which will secure' a iirm attachment for the leg without mutilating the chair-seat or other article.

lt is also my object t0 provide a joint which will admit of the ready removal of the leg, so that in heavy articles-suoh as pianos and heavy upholstered chairs, sofas, &o.the legs may be detached to economize space in ship- Pmg# Besides its advantages as a furniture-joint, my invention is of especial value in the construction of chairs, and in the accompanying drawings, forming part of this specification, I preferably show the same as applied in joining the chair-leg to the seat.

Referring to the drawings, Figure 1 is a side elevation, partly in section, showing the ap' plication of my invention in joining the leg to the chair-seat. Fig. 2 is a rear elevation, partly in section'. Fig. 3 is a perspective view of the legsocket holder or rest, and Fig.4 is a sectional view of the bifnreated leg-socket with an annular clamp shown partly in section.

A denotes a Chairseat, and c c chair-legs.

B is a raised dovetailed rest or holder for the leg-socket.

D is a bifurcated legsocket with an elongated dovetailed head, the prongs being provided with teeth a a.

d d d are screws to secure the socket-holder to the chair-seat.

b is a set-screw.

rllhe socket-rest B and annular clamp C may be made of cast-iron, and the leg-socket D of malleable cast-iron. The socket-rest B, as

shown in Fig. 8, has raised receding side walls (No model.)

and a perpendicular end wall, and it issecured to the under side of a chairseatY by screws. The legsocket D, as shown in Fig. 4, is bifurcated, the forks being curvilinear to conform to the chair-leg, and, being of thin malleable iron, admit of bending to clamp the chair-leg. The forks are spread gradually from the head of the socket downwardly, and their inner walls are provided with teeth a a. The head ofrthe'leg-socket is elongated and dovetailed to fit the socket-rest B, as shown in Figs. l and 2. The annular clamp C is a band gradually increasing in diameter downwardly, as shown in Fig. 4, and rides upon the outer walls of the leg-socket D, serving to clamp the prongs or forks of the same to the chairleg by being forced down over the prongs.

My invention is applied as follows: The bifurcated socket D embraces the head of the chair-leg, which is first slotted to receive the teeth a a. The annular clamp c is then placed over the head of the socket and forced down on the prongs or forks until it clamps them tightly upon the leg, the teeth a a taking hold at the same time. The socket,with the leg attached, is theny inserted in the dovetailed socket-rest B. The set-screw b is then placed in position to hold the leg-socket D in place and prevent it working out the open end of the socket-rest, the opposite end of which is closed, as shown in Fig. 3;

It is evident that I secure the leg to the chair without cutting holes in the seat for the legs,
